本發明係為一種旋轉類的傳動元件，尤指一種具保持器的軸承。 The invention is a rotating transmission element, in particular a bearing with a retainer.

請參閱第一圖及第二圖所示，為現有軸承包含有一內環(1)、一外環(2)、一保持器(3)及複數滾珠(4)，該外環(2)係間隔地置於內環(1)的外圍，該保持器(3)設於該內環(1)與該外環(2)之間，而該保持器(3)係由兩片式具有複數凹部(311)的環狀片(31)組成，兩該環狀片(31)係藉由複數固定件(G)連結固定，兩該環狀片(31)之凹部(311)係構成複數個供滾珠(4)設置的容置孔(32)，而該些滾珠(4)係可於該容置孔(32)轉動地設於該保持器(3)上，並與該內環(1)與外環(2)接觸，然而該容置孔(32)之保持面(321)係相對滾珠(4)的表面輪廓設置，故並無法提供潤滑油儲存於保持面(321)與滾珠(4)之間，軸承於運行過程中，滾珠(4)與內環(1)的滾動溝(11)、外環(2)的滾動槽(21)接觸摩擦，其摩擦力大如果又潤滑性不佳，產生的摩擦熱高，因此大幅降低軸承的精度及使用壽命。 Referring to the first and second figures, the existing bearing includes an inner ring (1), an outer ring (2), a retainer (3) and a plurality of balls (4), the outer ring (2) Interposed at the periphery of the inner ring (1), the retainer (3) is disposed between the inner ring (1) and the outer ring (2), and the retainer (3) is composed of two slices having a plurality The annular piece (31) of the concave portion (311) is composed of two annular pieces (31) which are connected and fixed by a plurality of fixing members (G), and the concave portions (311) of the two annular pieces (31) constitute a plurality of The accommodating hole (32) is provided for the ball (4), and the balls (4) are rotatably disposed on the retainer (3) at the accommodating hole (32), and the inner ring (1) ) is in contact with the outer ring (2), however, the holding surface (321) of the receiving hole (32) is disposed opposite to the surface contour of the ball (4), so that lubricating oil cannot be stored on the holding surface (321) and the ball ( 4) During the running of the bearing, the ball (4) is in contact with the rolling groove (11) of the inner ring (1) and the rolling groove (21) of the outer ring (2), and the friction is large if it is lubricious. Poor, the resulting frictional heat is high, thus greatly reducing the accuracy and service life of the bearing.

有鑑於上述問題，本發明主要目的在於：研發一種具潤滑油 儲存結構的軸承之保持器。 In view of the above problems, the main object of the present invention is to develop a lubricating oil A retainer for the bearing of the storage structure.

為達成上述之目的，本發明係為一種具保持器的軸承，係包含：一內環，其具有一滾動溝；一套設於內環外周的外環，其具有一對應該滾動溝設置的滾動槽，該滾動溝與滾動槽係構成一負荷路徑；複數滾珠；一環型的保持器，其設有複數個供滾珠設置的容置孔，各該容置孔係由複數個相對應的U型狀的半保持部構成，且兩相對設置的半保持部之U型的開口係交錯設置，兩該半保持部分別設有相對應U型的半油溝，兩該半油溝係構成一油溝，該滾珠與該油溝之間係形成一潤滑油儲存空間。 In order to achieve the above object, the present invention is a bearing having a retainer comprising: an inner ring having a rolling groove; and a set of outer rings disposed on the outer circumference of the inner ring, the pair having a pair of rolling grooves a rolling groove, the rolling groove and the rolling groove system form a load path; a plurality of balls; a ring type retainer, which is provided with a plurality of receiving holes for the balls, each of the receiving holes is composed of a plurality of corresponding U The semi-retaining portion of the shape is configured, and the U-shaped openings of the two oppositely disposed semi-retaining portions are staggered, and the two semi-retaining portions are respectively provided with corresponding U-shaped semi-oil grooves, and the two semi-oil grooves constitute one The oil groove forms a lubricating oil storage space between the ball and the oil groove.

較佳的，該半保持部相對該容置孔分別設有兩半保持面，該半保持面一端係與該半油溝連接，另一端係朝徑方向延伸並呈漸縮設置，一該容置孔的兩該半保持面係構成一ㄑ字型，以將該滾珠保持於該容置孔。 Preferably, the semi-retaining portion is respectively provided with two semi-retaining faces with respect to the receiving hole, one end of the semi-retaining surface is connected to the semi-oil groove, and the other end is extended in the radial direction and is tapered. The two holding surfaces of the holes are formed in a U-shape to hold the balls in the receiving holes.

較佳的，該半油溝係為一四分之一圓，該圓之半徑係介於0.5~2mm，該油溝為一半圓形。 Preferably, the semi-oil groove is a quarter circle, the radius of the circle is between 0.5 and 2 mm, and the oil groove is semicircular.

藉此，本發明由該保持器所設置的半保持部之開口相互交錯設計，以擾動潤滑油於保持器的容置孔流動，再者由各該半油溝的設計得以讓潤滑油留存於滾珠與半油溝所形成的儲存空間，以讓滾珠得到充分的潤滑。 Thereby, the opening of the semi-retaining portion provided by the retainer of the present invention is alternately designed to disturb the lubricating oil flowing in the receiving hole of the retainer, and the design of each of the semi-oil grooves allows the lubricating oil to remain in the lubricating oil. The storage space formed by the balls and the semi-oil grooves allows the balls to be fully lubricated.
